Predictika · Air handling unit configurations
An AI sales agent prepares a configuration for a modular air handling unit: size, heat recovery, fans, coils, filters, dampers and base frame. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the catalog rules and returns a verdict, every reason and the figures it computed.
This validator models Geniox air handling unit configurations from the North American Geniox catalog, not just the scenarios shown below.
Any Geniox configuration that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Systemair does not publish Geniox prices, so this validator produces no price build-up or line-item quote), airflow-to-size matching and performance calculations (the catalog leaves those to the SystemairCAD tool), cross flow plate exchangers (the catalog gives two different size limits), other Systemair unit ranges, and controls.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| Options that exist only for some unit sizes: counter flow exchanger, XL impeller, supporting legs, forklift frame | Only with care A product rule per option and size range. It works, but with 16 sizes every option is another set of rules to maintain against the catalog. | The size and every option are in one request and every size limit is checked together. |
| External damper types that depend on the unit size | Only with care Each damper type has its own size range, so each needs its own rule and the ranges have to be kept in step with the catalog. | The damper type and the size are checked against all the ranges in one pass. |
| Outdoor units that must sit on the 8.6 inch base frame, and a carbon filter that needs an F7 filter in front | Only with workarounds Both depend on a choice on one line and another choice on a different line, so they need cross-line rules that interact with the rest. | Every choice is in one request, so the conflict is found whichever order the choices arrive in. |
| Stated panel filter and damper motor counts that must match the catalog for the size | Only with care A stated figure is a free-entry field; a rule can compare it with a computed count, but every size needs its own lookup to be written and kept current. | The stated counts travel with the configuration and are compared with the computed counts on every call. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the configuration is saved or a step is completed, so a rep often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.
| 1 | Size 25 is not one of the Geniox sizes (10, 11, 12, 14, 16, 18, 20, 22, 24, 27, 29, 31, 35, 38, 41, 44). |
| 2 | The airflow of 120,000 m3/h is outside the Geniox range of 750 to 110,000 m3/h. |
| 3 | The counter flow plate heat exchanger is available only for Geniox sizes 10 to 20; the quote has size 22. |
| 4 | The sorption hybrid rotary heat exchanger is offered only in versions A, B and D; version C is not available. |
| 5 | The XL plug fan impeller class exists only for Geniox sizes 35 to 44; the quote has size 31. |
| 6 | The MAX (full-size) heating coil variant is offered for hot water and condensation coils only, not for electric heating. |
| 7 | Copper and seawater resistant aluminum (AlMg) fins are offered only with 1/2 inch and 5/8 inch tubes; the coil has 3/8 inch tubes. |
| 8 | A hot water temperature of 130 degrees C is above the standard limit of 100 degrees C; coils for up to 130 degrees C are available and a person should confirm the special design. |
| 9 | Hot water heating coils are offered up to 130 degrees C; the quote has 131 degrees C. |
| 10 | Water coils have a maximum working pressure of 10 bar; the quote has 11 bar. |
| 11 | An air temperature of 55 degrees C is above the standard maximum of +40 degrees C; the special design for up to +60 degrees C should be confirmed by a person. |
| 12 | The unit air temperature range is -40 to +60 degrees C; the quote has a maximum of 65 degrees C. |
| 13 | The unit air temperature range is -40 to +60 degrees C; the quote has a minimum of -45 degrees C. |
| 14 | The casing operating pressure is 0 to 2,000 Pa; the quote has 2,100 Pa. |
| 15 | Outdoor units are always supplied on the 8.6 inch base frame; the quote has a different base. |
| 16 | Supporting legs are offered only for indoor units of Geniox sizes 10 to 18. |
| 17 | With the forklift base frame each section must be 700 to 2,882 mm long; the quote has a 2,900 mm section. |
| 18 | The base frame with forklift holes is an option for Geniox sizes 10 to 31; the quote has size 35. |
| 19 | The external damper type on the quote is not offered for Geniox size 22 (types 1 and 2: sizes 10 to 24; type 3: sizes 10 to 20; type 4: sizes 10 to 31). |
| 20 | The external damper type on the quote is not offered for Geniox size 35 (types 1 and 2: sizes 10 to 24; type 3: sizes 10 to 20; type 4: sizes 10 to 31). |
| 21 | A carbon filter needs an ePM1 60 percent (F7) filter in front of it; the quote has none. |
| 22 | The carbon filter limit is 70 percent relative humidity; the air at the filter is 75 percent. |
| 23 | An ePM1 85 percent (F9) bag filter must be on the positive pressure side of the supply air unit; the quote places it on the suction side. |
| 24 | The virucidal bag filter is for return air or as the second filter stage in the supply air; the quote places it as the first stage in the supply air. |
| 25 | Humidifier elements come in thicknesses of 3, 4, 5 and 6 inches; the quote has 7 inches. |
| 26 | Sound attenuators come in lengths of 600, 900, 1,200, 1,500 and 1,800 mm; the quote has 1,000 mm. |
| 27 | The quote states a panel filter count of 10; a Geniox of this size has 8. |
| 28 | The quote states a damper motor count of 2; the internal dampers of this size need 1. |
